1. Sift the Citric Acid and Baking Soda (Bicarbonate) into a bowl. Sifting removes any clumps from either and will ensure a smooth and even consistency in your finished bath bombs. If you’re using a scale to measure your ingredients, place the bowl with your fine mesh sifter nested inside directly on top and pour the ingredients in. We like saving time!
2. Pour your quick oats into the bowl and stir really well. Next, drizzle your essential oils on top and mix everything really well. I find that using my hand is far better than a spoon since I can break any clumps with my fingers and make sure that the fragrance is evenly dispersed.
3. Now here comes the trickiest part to describe. You’ll want to spray this mixture with Witch Hazel until it reaches a slightly damp consistency. The best way to describe this is maybe damp sand on the beach that is just starting to dry out. With my mini spritzer I spray three squirts and then mix really well with my hand. I keep adding three more squirts and mixing until the consistency feels right. What you’re looking for is the mixture holding form when you squish it into a ball in your hand. With my mini sprayer this took eighteen squirts though of course your sprayer may be different.
4. Bath bomb moulds come in two pieces with one side fitting inside the other. Take the half that has the lip that fits inside the other half and place a few dried flower petals at the bottom. These will be the pretty decoration you see on the top of the bath bomb so arrange the flowers in an attractive manner.
5. Take a handful of the damp bath bomb mixture and carefully pour it on top of your flower arrangement. Use both of your thumbs to compact the mixture down but leave a hollow in the centre. Fill this hollow with more dried flower petals and then sprinkle more bath bomb mixture on top. Don’t compress the top mixture just yet and set this half of the mould down for a moment.
6. Take the second half of the mould in your hand and fill it with bath bomb mix. Press down with your thumbs to compress but don’t leave a hollow this time. Top it off with a bit more bath bomb mix and like the other half, don’t compress this top layer yet.
7. Carefully pick up both halves of the moulds and place them together. Press firmly so that the mixture from both halves compresses together.
8. Pull the ‘bottom’ mould off your bath bomb then gently tap the bomb out of the second half and onto a surface where it can dry. If your surface is too hard, it’s likely that the bottom of your bath bomb will flatten so I dry my own bombs on a folded towel with a sheet of cling film on top.
Depending on size, Bath Bombs can take anywhere from twelve to twenty-four hours to dry. After this, you’re able to package them up, set them somewhere to scent the room, and eventually pop them into your bath for fizzy and fragrant relaxation.
